Funds from this grant support a series of projects to increase the usefulness of the Isis Bibliography of the History of Science, the oldest and largest bibliography in its field and an invaluable resource to historians of science worldwide.  Using grant funds, Isis Bibliographer Stephen Weldon and his team will spearhead a series of initiatives designed to bring the ISIS Bibliography more fully into the digital era, including retrospective digitization, data extraction, and cleanup of the existing bibliography; the development of new researcher-facing tools and interfaces; “community-sourced” mechanisms for maintaining the bibliography going forward; and a mini-grant program to incentivize novel or innovative ways of utilizing the bibliography as a scholarly resource.
